Growing adenium from seed is an easy way to propagate the species. Adenium, sometimes called desert rose, grows slowly and will not grow flowers for the first four to five years. Adenium has a wide, round base that sprouts a number of branches. The flowers of adenium can be white, pink or purple. The plant can be grown in USDA zones 11 and 12.
Soak adenium seeds for two to four hours to prepare them for germination. Place the adenium seeds between two paper towels that are drenched with water. Keep checking the paper towels to make sure they don’t dry out.
Plant the adenium seeds in a small plant pot that is filled with a commercial cactus mix. The mix should drain well to prevent any damage to the roots. Place the seeds horizontally into the soil and sprinkle a ¼-inch layer of loose dirt over them.
Water the seeds gently, soaking the soil without driving the seeds downward. This can be done by using a slow trickle on one side of the pot to spread through the soil.
Place the pot in a window sill where it will get direct sunlight, or use a grow light during daylight hours.
Keep the soil in the pot moist but not soaked. The seeds need moisture to germinate, but too much water can cause seed rot. It will take up to three weeks for the seeds to germinate.
Fertilize the seedling once it sprouts. Give adenium seedlings a fertilizer that contains a high percentage of phosphates every two weeks.
Water regularly, never allowing the soil to dry. The pot should allow drainage through the bottom because adenium is prone to rot.
